OIL-PUMP :MEcHANIsM.

Application filed July 28,

The present invention relates to a means whereby the well known oil gearpump may be utilizedin conpinction with a Ford engine for circulatingthe oilto maintain the front sumps filled, soas t prevent the burnin'gout of bearings when the englne s mg clined upwardly and forwardly, suchas when the automobile is climbing. a hill.

in the provision of a mechanism of this na- An important object of-theinvention lies ture which may be incorporated with the standard parts ofthe engine without any extensive alterations.

A still furthervery important object of the invention'is to provide amechanism of this nature which is exceedingly simple in itsconstruction,strong and durable, inex pensive to manufacture, efficientand reliable in operation, easy to assemble and disassemble, andotherwise well adapted to the purpose for which'it is designed.

With the above and numerous other objects in view as will appear as thedescrip tion proceeds, the invention resides in certain novel featuresof construction, and in the combination and arrangement of parts as willbe hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of an engine of the wellknown Ford type, showing my im-'. proved mechanism associated therewith,

Fig. 2 is a rear elevation of the pump and supporting means,

Fig. 3 is a side elevation thereof, and Fig. 4 is a sectional elevationof the outlet attachment of the pump.

Referring to the drawing in detail, it will be seen that I haveillustrated the well, known type of Ford engine 5 which is provided withthe usual front plate 6 which is held in place by bolts one of which isshown at 7. A breather neck 8 extends from the plate in the usual wellknown manner. The fan shaft is indicated by the numeral 9 and isjournaled in the bearing 10 on the arm 11 which is mounted on the bolt7. A grease cup 12 is engaged in the bearing 10 in the usual manner.

The numeral 14 denotes a well known type of gear pump having the usualdrive gear 15. The'numeral 16 denotes an L-shaped bracket havingslot-ted ends. One slotted end of the bracket 16 is pierced by the bolt7 and the 1926. Serial Nd, 125,561.

other slotted endithereof is pierced" a screw .17 or like fasteningelement which is V engaged with the gear pump 14. A plate 18 is providedwith'right angularly extending end portions 19 and 20 extending inopposite directions, and slotted; A screw 21 pierces the slotted end 19and engages the. gear pump. 14;. The grease cup 12 'pi'erces the otherslotted end 20 and holds it in engagement with the bearing 10 of the arm11'.

A gear 22 is fixed onthe fanv shaft 9 in any suitable manner and mesheswith the gear 15. A pipe 24 leads from therear of the crank case of theengine forwardly and is bent as at 2 5 and rises upwardlyfor engagementwith the intake 26 of the gear pump 14L An outlet attachment 27 isprovided on the pump and includes a valve seat 28 intermediate itse'ndsfor receiving a ball valve 29 normally'jheld in place by a'ispring 30.The' spring 30 is tensioned and held inplaceby asuitable cap 21. I.

An outlet branch 32 is extended from the attachment 27 to one side ofthe valve seat 28 while a gauge extension 33 extends from the attachmentto the other side of the valve.

seat; Thus the pressure is delivered to the gauge at all times. Thevalve 29 functions as a check valve. A pipe 34 leads from the outletbranch 32 to a cap 35 on the breather pipe 8. Itwill thus be seen thatwhen the engine is in operation, the gear 22 will operate the gear pump,thereby pumping the oil from the rear of the crank case through the pumpand into the breather and filling pipe 18, thereby maintaining the frontsump filled, so

that the splash oil system will operate to lubricate the forward portionof the engine particularly when said engine is inclined upwardly andforwardly, such as when the automobile is climbing a hill.

7 It is thought that theoperation, advantages, and construction of thisinvention will now be clearly understood by those skilled in this artwithout a more detailed description. The present embodiment of theinvention has been'disclosed in detail merely by way of example since inactual practice it attains the features ofv advantage enumerated asdesirable in the statement of the invention and the above description.Numerous changes in the details of construction, and in the combinationandarrangement'of parts may be resorted to without departing from theing, and an oil cup associated with the bearspirit or scope of theinvention as hereinafter claimed, or sacrificing any of its advantages.

Having thus described my invention, wha I claim as new is 1. Means forsupporting an oil pump on an engine; wherein the engine includes a crankcase, a timing gear cover plate, bolts holding the cover plate to thecrank case,

an arm on one of said bolts terminating-in a bearing, a fan shaftjournaled in the hearing; comprising an L-shaped bracket having its endsslotted, one slotted end being pierced by said bolt which mounts thearm, a screw piercing the other slotted end of the bracket for engagingthe same with the oil pump, a plate having offset slotted ends, one ofthe slotted ends of the plates being pierced by the oil cup, a screwpiercing the other slotted end of the plate and engaged with the gearpump.

2. Means for supporting an oil pump on an engine; wherein the engineincludes a crank case, a timing gear cov vr plate, bolts holding thecover plate to the crank case, an arm on one of said bolts terminatingin a bearing, a fan shaft journaled in the bearing, and an oil cupassociated with the bearing; comprising an L-shaped bracket having itsends slotted, one slotted end being pierced by said bolt which mountsthe arm, a screw piercing the other slotted end of the bracket forengaging the same with the oil pump, a plate having offset slotted ends,one of the slotted ends of the plates being pierced by the oil cup, ascrew piercing the other slotted end of the plate and engaged with thepump, an outlet associated with the gear pump, a pipe connecting theoutlet with the gear cover plate, and an inlet provided on the gear pumpand a pipe connecting the inlet with the rear of the crank case of theengine.

3. Means for supporting an oil pump on an engine; wherein the engineincludes a crank case, a timing gear cover plate, bolts holding thecover plate to the crank case, an arm on one of said bolts terminatingin a bearing, a fan shaft 'journaled in the bearing, and an oil cupassociated with the hearing; comprising an L-shaped bracket having itsends slotted, one slotted end being pierced by the bolt holding the armon the cover plate, a screw'piercing the other slotted end of thebracket for engaging the same with the oil pump, and a plate having anopening pierced by the oil cup and another opening, a fastening elementpiercing the other opening for engaging the plate to the crank case.

In testimony whereof I affix my signature.
